2. 1. Functional PVC Additives : Core-Shell Nanoparticle and Renewable Resource Plasticizers

   Author : Bo Yin; Minna Hakkarainen; Mikael Skrifvars; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PVC; nanocomposite; nanoparticle; core-shell; plasticizer; renewable resources; isosorbide; glucose;

   Abstract : Several functional poly(vinyl chloride) (PVC) additives were designed: PVC plasticizers made from renewable resources as alternatives to traditional phthalate plasticizers and core-shell nanoparticle-plasticizers with the aim to design an additive that can improve several mechanical properties simultaneously. Monomeric and oligomeric PVC plasticizers based of isosorbide and glucose were synthesized. READ MORE

4. 2. Rigid PVC Nanocomposites - Influence of Processing and Montmorillonite Treatment

   Author : Karin Sterky; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; non-ionic; processing; PVC; interaction; nanocomposite; montmorillonite;

   Abstract : Poly(vinyl chloride) (PVC) is a material extensively used in various applications due to its lowcost, durability, and chemical resistance. There are, however, still improvements that can bemade to the material. READ MORE

5. 3. An Environmental Approach to PVC Stabilisation

   Author : Paul Clucas; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic stabiliser; base catalysed dehydrochlorination; colour improvement ; dehydrochlorination stability; polymer-bound stabiliser; intrasequence lactonisation; co-stabiliser; PVC stabilisation; colour stability; labile chlorine substitution; neighbouring group participation;

   Abstract : We were interested in investigating the stabilisation behaviour of 6-aminouracils, a new class of heavy metal free thermo-stabiliser for PVC. We have therefore investigated the performance and mechanism of stabilisation for 1,3-dibutyl-6-aminouracil, both alone, and in combination with a sodium perchlorate co-stabiliser. READ MORE

6. 4. Personality, Health and Mortality of Workers in a PVC Production Plant in Sweden A longitudinal study

   Author : Margareta Ardeberg; Miljö- och energisystem; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mortality; disease; recovery; personality alterations; solvents exposure; PVC; polyvinyl chloride; Sjöbring personality psychology; behavioural toxicology; MNT scale; MFS scale; Eysenck; Psychology; Psykologi;

   Abstract : A longitudinal study was initiated in a PVC production plant in 1967. It was repeated in 1987. A cohort of 101 workers was followed. The aim of the 1967 study was, after a heavy rise in absenteeism and sick leave, to analyze perceptions of work environment and health. READ MORE

   Abstract : The potential for recycling various polymeric materials contained within buildings constructed in the late 1960s and 1970s in Sweden was investigated during the course of this work. Three residential blocks were studied to establish the quantity of materials available for recycling, to investigate the difficulty in and time needed for the dismantling of the buildings, the degree of purity of the materials, and the possibility of separating the materials.
